RSPF12JB10R0

Overview

The RSPF12JB10R0 is a fixed metal oxide film resistor manufactured by Stackpole Electronics Inc. It features an axial through-hole mounting configuration with a resistance value of 10 ohms and a tolerance of ±5%. The component has a power rating of 0.5W (500mW) at 70°C and a maximum working voltage of 400V. It exhibits a temperature coefficient of +350ppm/°C and operates within a temperature range of -55°C to 155°C. The unit is flameproof, moisture-proof, and RoHS compliant.

Feature Summary

• Flameproof design utilizing robust metal oxide film elements for enhanced safety in high-power duty cycles
• Moisture-proof construction ensuring stability in humid environments
• Axial leaded package suitable for standard through-hole PCB mounting

Applications

• Power limiting circuits requiring flameproof safety standards
• General purpose electronic equipment with through-hole assembly requirements
• Industrial control systems operating under moderate thermal loads

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm tolerance and packaging variations. Confirm RoHS compliance status for current production runs. Check manufacturer specifications for cut-to-length availability if standard axial leads are unsuitable for the target application.

Selection Notes

Select this component when a 0.5W metal oxide resistor with flameproof characteristics is required. Ensure the circuit voltage does not exceed the 400V maximum working voltage limit. Verify that the ±5% tolerance aligns with the circuit's precision requirements and that the +350ppm/°C temperature coefficient is acceptable for the operating environment.

Part Context

This part belongs to the RSPF series of flameproof power resistors from Stackpole Electronics. The series utilizes metal oxide film technology to provide durability and safety in applications where standard resistors might fail catastrophically. The RSPF12 designation indicates the 0.5W power rating class within this product line.

Replacement Considerations

Direct substitutes must match the 0.5W power rating, 10 ohm resistance, ±5% tolerance, and axial form factor. Verify that replacement components also meet the 400V maximum working voltage and flameproof design requirements to maintain system safety integrity.
